MACHINE FOR USE IN STROPPING RAZORS.

SPECIFICATION forming part of Letters Patent No. 714,622, dated November25, 1902.

' Application filed June 30, 1902.

I0 all whom, it nwty concern:

Be it known that I, WILLIAM TAPP, a sub Bristol, England, have inventednew and useful Improvements in Machines for Use in Stropping Razors, ofwhich the following is aspecification.

My invention relates to that type of machines for use in the stroppingof razors in which an oscillatory support is provided for holding therazor, and the provision for stropping it consists of a flexible band,by reciprocatory endwise motion of which band oscillation of therazor-support is produced, causing the two sides of the razor-blade tobe alternately pressed against and acted on by the said band. 7

My said invention has for its principal objects to improve theconstruction of this class of machines by simplifying the arrangement ofparts and to provide for thorough efficiency in operation, which objectsI attain by dispensing with the parts heretofore provided for guidingthe stropping-band contiguously to the oscillatory razor-support and byforming the said support so that the back of the blade of a razor whenplaced in the machine is entirely free and also (by preference) so thatthe position of the said blade relatively to the stropping-band is suchas to insure a heel-topoint action of the said band on the blade.

I will further describe my invention with reference to the accompanyingdrawings.

Figure 1 is a side View, Fig. 2 a front View, and Fig. 3 a plan, of amachine of the aforesaidtype embodying'my said improvements. Figs. 4 and5 are sectional views showing the parts of the machine above the line A,Fig. 1, in difierent positions.

In the following description the several parts of the machine arereferred to by the letters markedon the"drawings,'the same letters ofreference being used to indicate the same parts in all the figures.

a is a screw-clamp constituting the base of the machine and admitting pfthe fixing thereb c are rods or pillars secured at their lower ends inthe base a and supporting the acting parts of the machine, which are anoscillatory razor-holder and means (hereinafter termed the oscillator)whereby the required mo- Serial No.113,829. (No model.)

tion is communicated to the razor-holder from the stropping-band,theposition of which relatively to the aforesaid parts of the machine isindicated by the broken linesddin Figs. 1 and 3. The said razor-holderconsists of a screwclip 6 for receiving the tang of the razor and an armf, having jaws at its free end, in which clip and jaws the razor to bestropped is placed in the position indicated by the broken lines 9 inFig. 1. The said parts e f are both carried by a tube or sleeve h,surrounding the pillar b and capable of turning thereon. The oscillatorconsists of a semitube 1 having elliptical ends j is, which are engagedwith the pillar c and have formed in them slots or notches Z m, withwhich the free ends of arms n 0, projecting from the razor-holder, areengaged.

p q are disks affixed, respectively, to the part j of the oscillator andto the base a and serving to keep in place the stropping-band, which byits bearing on the oscillator communicates motion thereto when actuatedduring use of the machine.

In order to strop a razor by means of the said machine, the razor isplaced in the oscillatory holder, as indicated at g in Fig. 1, andsecured by means of the screw of the clip 6, and the stropping-band isplaced as indicated at d in Figs. 1 and 3, and. its two ends are pulledalternately, the band being kept sufficiently in tension to cause motionto be imparted by it to the oscillator, the motion of which iscommunicated to the razorholder by the engagement of the parts lmand n 0until the said parts become interlocked, after which during theremainder of each pull on the band it slips on the oscillator and rubsor strops the razor-blade on the side presented to the band by theturning of the razor-holder. The manner in which the engaged parts ofthe oscillator and the razorholder interlock after being partiallyturned by the first portion of each pull on the band is clearlyillustrated by the sectional views, Figs. 4: and 5.

In consequence of the stropping-band being unsupported by or having nobearing on any part of the machine except the oscillator the elasticityof pressure on the razor of the said band when in tension is in no'wayimpaired,as it is in machines having intermediate guides or supports forthe band to bear against, and in consequence of the razorholder being soconstructed as to engage only with the tang and point end of the bladepressure of the stropping-band against the whole of each side or face ofthe blade is insured.

Although I prefer to provide for support of the razor at such an angleas to insure a heelto-point action of thestropping-band, I do not limitmyself thereto, as the other features of my invention are advantageousin the case of machines wherein the razor-blade is supported at rightangles to the direction of motion of the stropping-band.

Where desirable, provision for supporting the machine during use bymeans of hooks, as in some other machines of the aforesaid type, may besubstituted for the screw-clamp illustrated.

What I claim as my invention, and desire to secure by Letters Patent,is-

l. In a device for stropping razors, the combination of a frame, twopillars in said frame, a sleeve on each of said pillars, means forattaching a razor to one of said sleeves, a pair of jaws on the other ofsaid sleeves, a tongue on said razor-supporting sleeve projectingbetween said jaws, and a razor-strop passing around the sleeve that isprovided with jaws.

2. In a device for stropping razors, the

combination of a frame, two pillars carried by said frame, a sleeve oneach of said pillars, a razor-support on one of said sleeves, saidsupport consisting of a tang-end holder and a point-end holder, jaws onthe other of said sleeves, a tongue on said razor-supporting sleeveprojecting between said jaws, and

a razor-strop passing around the sleeve that is provided with jaws.

3. In a device for stropping razors, the combination of a frame, twopillars carried by said frame, a sleeve on each of said pil- 1ars,'arazor-support on one of said sleeves, said support consisting of atang-endholder and a point-end holder, and said point-end holderextending a greater distance from said sleeve than said tang-end holder,jaws on the other of said sleeves, a tongue on said razorsupportingsleeve projecting between said jaws, and a razor-strop passing aroundthe sleeve that is provided with jaws.

4. In a device for stropping razors, comprising a reciprocatingstropping-band, and an oscillatory razor-support, a razor-holderconsisting of a tang-end-receiving part and ofa pointend-receiving partin advance of the tang-endreceiving part.
